Hi all,I tried to upgrade to LabVIEW 2009 from LabVIEW 8.6 on 64-bit windows XP machine. Following about a 2 hour removal of 8.6 and subsequent installation of LV 2009 it turns out that the device drivers are not compatible with a 64-bit machine. On launching LabVIEW 2009 (32-bit) an error box appears stating that it is corrupt or missing files and to correct this using control panel etc. I have tried this and still the same error occurs and LV refuses to start. All the license files are correct and the compnents are activated. Anyone know how to fix this? Or should I go back to 8.6 and cancel my upgrade subscription? Secondly, I am using a firewire camera and was informed that Ni-IMAQ legacy are no longer supported and to go to ni.com/ifo and enter legacy1394 to see how to download drivers etc for this. I end up on a page that says "not authorized". Any help gratefully appreciated.

Dear Leeser, Since 2006, National Instruments has annually released a new version of LabVIEW each August to establish a more predictable release schedule. This gives LabVIEW users the ability to better plan new developments and upgrades to future releases. In addition, this year, NI changed the product name to LabVIEW + year (for example, LabVIEW 2009) reflecting the year of the release and setting the stage for future annual releases of LabVIEW. Please visit the following site for details on this: http://www.ni.com/labview/product_lifecycle.htm With regards to Windows XP 64-bit this is not supported officially by any NI hardware drivers or software. For a list of drivers that have been known to work please see the link below: http://joule.ni.com/nidu/cds/fn/p/sn/n19:Windows.7809/lang/en Now with Windows Vista x64 there is an excellent "windows on windows" 32-bit compatibility mode which allows our drivers to function properly. With regards to LabVIEW 2009 there is now a dedicated 64-bit version which is advised for use with 64-bit operating systems. Again Windows XP 64-bit is not officially supported. Further details of Windows XP x64 compatibility can be found in the following article: http://digital.ni.com/public.nsf/allkb/C4EC0C87B6D70AA886256E61006568C8?OpenDocument I hope that this helps to clarify a few things. Kind Regards,
